A significant volume of research demonstrates that out-of-school learning activities enhance student development in terms of cognitive, affective and social outcomes. However, there is also evidence that the opportunity to engage in these activities has been severely reduced in recent years. This paper explores the extent to which the provision of such opportunities is unevenly distributed— spa...

Talk 1 (18.10.2017 – Gesina Schwalbe): Overview of some classical results. Recall the classical theorems of Freudenthal and Hurewicz and some elementary calculations of homotopy groups of spheres. Recall the definition of the stable homotopy groups of spheres and explain the ring structure. Show that the Hopf maps are stably essential, i.e. not stably null-homotopic, using Steenrod operations. ...

We provide a nonparametric method for the computation of instantaneous multivariate volatility for continuous semi-martingales, which is based on Fourier analysis. The co-volatility is reconstructed as a stochastic function of time by establishing a connection between the Fourier transform of the prices process and the Fourier transform of the co-volatility process. A nonparametric estimator is...

Good language learners slot in a repertoire of strategies and when language tests are at stake, test-taking strategies and test-wiseness pave pay to a prolific outcome. Among such tests, TOEFL iBT seems to be a prerequisite to academic success and a nightmare many Iranian students struggle with. Therefore, the aim of the present study was to raise awareness about the type of questions in iBT, b...

Despite the clear long-term benefits of spaced practice, students and teachers often choose massed practice. Whether learners actually fail to appreciate the benefits of spacing is, however, open to question. Early studies (e.g., Zechmeister & Shaughnessy, 1980) found that participants' judgments of learning were higher after massed than after spaced repetitions, but more recent studies have fo...

Although the mnemonic benefit of spaced retrieval is well established, the way in which participants naturally space their own retrieval is relatively unexplored. To examine this question, a novel experimental paradigm was developed in which young and healthy older adults were given control over the frequency and timing of retrieval practice in the context of an ongoing reading task. Results sh...

Expanding retrieval practice refers to the idea that gradually increasing the spacing interval between repeated tests ought to promote optimal long-term retention. Belief in the superiority of this technique is widespread, but empirical support is scarce. In addition, virtually all research on expanding retrieval has examined the learning of word pairs in paired-associate tasks. We report two e...

This study used a novel method to explore different schedules of spacing in young EFL learners. In doing so, we taught young EFL learners English–Farsi word pairs using different spacing schedules (massed vs. spaced). In the massed condition, learners studied five-word pairs in session one and five-other word pairs one week later. In the spaced condition, the learners studied 10-word pairs in s...

Abstract Spaced and interleaved practices have been identified as effective learning strategies which sometimes are conflated a single strategy at other times treated distinct. Learning sessions in studying information or practicing problems spaced time with rest-from-deliberate-learning periods between generally result better outcomes than massed practice without periods. Interleaved also cons...
